Title: Base isolation device
Inventor: MATSUKAWA HIROKAZU
IPC: E04B1/36
Filed: 1999-03-08
Abstract: PROBLEM TO BE SOLVED: To restrain horizontal displacement and force even in a light-weighted structure by providing a support post extended downward on the lower surface outside an upper plate outer peripheral part, a sliding member which enables at least one of a post lower end part and a lower plate upper surface, and a laminated body where an elastic layer and a rigid plate layer are alternately stacked in the vertical direction. SOLUTION: The upper end of a cylindrical support post 5 extended downward is fixed to the central part of the lower surface of an upper plate 1, and a sliding member 6 for horizontally supporting the upper plate 1 with the post 5 relatively to a lower plate 2 is provided between the lower end part of the post 5 and the upper surface of the lower plate 2. The whole peripheries of the outer peripheral parts of the upper and lower plates 1, 2 are connected by a cylindrical laminated body 15, and the laminated body 15 is formed by alternately bonding an elastic layer 15a and a rigid plate layer 15b in the vertical direction.  Thus, when force is applied in any direction at the time of an earthquake, horizontally sudden vibration is lightened by the sliding member 6 and restoring force is generated by shearing deformation of the laminated body 15 to function as damping force with the sliding frictional force of the sliding member 6. Thus, horizontal vibration can be restrained, and after the earthquake is ended, the upper plate 1 can be returned to the position before sliding.

Filed: 1986-03-18
Abstract: PURPOSE:To attain a free branching action between the machine instruction of a main memory and the microinstruction of a control memory device, by adding in series the addresses of the control memory device and the main memory. CONSTITUTION:The addresses of a main memory 1 and a control memory device 3 are given in series. The control is started to execute a machine instruction including a branch instruction and a branch destination address indicates the address of the device 3.

Abstract: PROBLEM TO BE SOLVED: To reduce the handing-over of change by reducing the account settlement of payment of merchandise price in cash for a customer to perform shopping at a store by composing a system of a main body for coin counting, interface part and magnetic card recording part. SOLUTION: The total amount of inserted cash and amount information recorded in a magnetic card is displayed on an amount display part 12. When the customer confirms the displayed amount and pushes an amount confirm button, new amount information or the date of utilization is written in the magnetic card on standby, its detailed statement is printed out of a detailed extracting port 14, and processing is finished by pushing a card eject button 17. The customer, who takes out the magnetic card, performs shopping inside the shop and settles the account of payment of merchandise. On the other hand, since a magnetic card computer reads the payment amount of merchandise through a POS system, etc., or operates the inputted total amount from the amount information recorded in the magnetic card, the account of payment of merchandise can be settled.  Thus, a clerk at each cash register can reduce the handing-over of change of small money or the like.

Title: Ozonizer
Inventor: OOTANI YUKIO
IPC: C01B13/11
Filed: 1979-05-18
Abstract: PURPOSE: To safely perform the operation of a water piping system for an ozonizer, by providing a piping device for preventing freezing in the water piping system.  
     CONSTITUTION: The cooling water outlet piping 7 and the cooling water inlet piping 8 of the cooling tower 5 are fitted with the electromagnetic valve-provided bypass pipings 10 and 11, respectively, and also the supplementary water intake 9 is fitted with the electromagnetic valve 12. When an ozonizer is stopped, the electromagnetic valve 12 is interrupted to stop the supply of supplementary water, and at the same time the electromagnetic valve-provided bypass pipings 10 and 11 are opened to discharge water. When the water in the pipings is completely discharged, the bypass pipings 10 and 11 are closed. At the beginning of operation, the electromagnetic valve 12 is opened and, after confirming the filling of sufficient water in the water piping system, the ozonizer is started. Thus, the danger of freezing can be eliminated because the water in the water piping can be completely removed after stopping the operation only by providing the electromagnetic valve-provided bypass pipings at the outlet and inlet of the cooling tower and also the electromagnetic valve at the supplementary water intake.

CONSTITUTION:This device is provided with a wiring 4, which is formed directly on a semiconductor substrate 1, and a diffusion layer 4 for a source and a drain, which is formed by diffusing impurities into the semiconductor substrate 1 when the wiring 4 is formed. A contact surface of the wiring 4 and the substrate 1 is used as a contact part as it is. A gate 3 part superposed on the wiring 4 is removed. For example, the wiring 4 is formed directly on the semiconductor substrate 1 by an epitaxial growth method, and the diffusion layer 5 is formed shallowly by diffusing impurities into the substrate 1 when the wiring 4 is formed by the epitaxial growth method. Further, a gate part superposed on the wiring 4 upon the formation of the gate 3 is removed after the formation of the gate 3 because it is needless. Hence, the fining of this device is enabled and a capacity formed between the wiring and the gate can be made small.

Abstract: PURPOSE:To miniaturize a circuit and to perform the phase adjustment with high accuracy. CONSTITUTION:A CPU 19 in a signal processing circuit 12' that takes rotational angular velocity information by processing a detection signal S detected by a photodetector 6, monitors an output of a detection signal of a second harmonic wave component S2 of the detected signal S and controls a signal generator 18 to adjust a phase of a phase modulation signal (fm) such that the output of the detection signal of the second harmonic wave component S2 becomes a level of zero. The phase of the phase modulation signal (fm) is shifted by wave length of 1/8 of the second harmonic wave component in the direction of a plus output side. It monitors an output of a detection signal of a fourth harmonic wave component S4 of the detected signal S to adjust the phase of the phase modulation signal (fm) such that the output of the detection signal of the fourth harmonic wave component becomes a level of zero. That is, the CPU has a function of phase adjustment whereby the phase of the phase modulation signal (fm) is shifted by wave length of 1/8 of the second harmonic wave component in the direction of a plus output side. The inclination of the output signal of the detection signal is the greatest in the vicinity of the level of zero so that the highly accurate detection can be achieved.
